Grey spot

[Danntbt]

I noticed a grey spot, appears regularly on my images when I shoot a pic with light grey background. Can anyone venture to advice me if this is caused by dust or the CCD? It appears to make its appearances even when I switch lenses, so probably not due to dust on the lens.
Thanks

BTW I am using a D70 and Nikon 80-200 F2.8 and Tokina ATX Pro 20-70 F2.8, and a Nikon Kit lens 18-70, periodically all these captured the grey spot now and then.

it could be a speck of dust on your sensor.

i had a small speck on mine too, only showed up when i used a large apperture number and shot with flash against a dark surface.

try using a blower on the sensor. it worked for me.

Have the same problem, and today went down to nikon service they clean it for me. Now everything is ok already...

be careful not to touch the ccd so you don't risk scratching it (obviously)

and do a quick one or u may end up exposing it to more dust.
